Application 1e`d ApriI 4, 1911. Serial No. 618,351.

C. LAIDLEY, residing at pact in size and of a strong and durableconstruction.

vFurther objects of the invention are, to provide `means for varying theamount of movement of the main controlling valve, so as to permit arelatively long or short duration of flushing; to provide means for ad'justing the flow of liquid through the outlet passage so as to permit ofthe 'flow being entirelycutoif if necessary; and to provide means foradjusting the flow of water through the inlet passage so as to permit-ofthe cutting oli 'of the How of water through said passage in order torepair or adjust the operating portions of the valve.l

The invention further consists in the features of construction and thecombination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal sectional view of the valveof the present invention; Fig. 2 is a view similar to Fig. 1, showingthe parts adjusted to permit of an increased movement of the maincontrolling valve; Fig. 3 is a section on line 3-3 of Fig. 2; Fig. 4 isa detail showing the controlling member for the outletport when it is inposition to close said port; Fig. 5 is a detail showing the mechanismfor closing the inlet port; and Fig. 6 is a view similar to Fig. 2,showing the main controlling valve in unseated position.

The device as shown in the drawings is inclosed within a casing 7,consisting of an upper enlarged portion 8, which terminates in a lowerreduced portion 9, the upper end of the casing being closed by a cap orcover 10. Inter-posed between the cap or cover and the upper edge of thecasing is a packing member 1l, and extending through said cap or coverare a series of locking members 12, which engage with a member 13 thatis mounted to revolve within the casing, andv in the county of Cook andState ofy which has its side walls cutaway at intervals, as shown moreclearly in Fig.` 3, to provide cut-ott members 14 for the water outletpassage. Secured to the lower end of the member 13 is a cup washer korother suitable packing 15, held in place by a ring 16 which is locked inposition by suitable locking members 17. The member 13, as shown, isscrew-threaded into the interior of the enlarged portion 8 of thecasing, and is capable of being raised and lowered therein. The purposeof this raising and lowering will be more fully hereinafter stated.

In addition to the up and down adjustment, the cup-shaped member may beturned within the casing so 'as to bring the cut-oil' members. 14 to thedesiredv position with respect to the outlet passage. When they are inthe position shown in Fig. 3, the outlet passage 18 is entirelyunimpeded and a free flow of water from the casing through the outletpassage is permitted. If, however, the members are turned so as to liein` a position at right angles to the position in which they are shownin Fig. 3, one of the cut-ott1 members 14 will be positioned across theoutlet passage 18, and, in this position it will cut off the iow ofliquid from the casing through the outlet passage. This completekcutting o of the flow of water through the outlet is to permit of theremoval of the iXture for the purpose of repair, substitution, etc.,without the danger of leakage of water ensuing by reason of thedisconnecting of the fixture from the outlet conduit of the iiushingvalve. By manipulating the member 13 so that theIcut-o members 14 assumepositions intermediate the two extreme positions formerly described,said cut-oli' members may assume a position so that the outlet passagewill be more or less restricted and the flow of water out from thecasing into the fixture more or less voluminous.

The cup washer 15 and the ring 16 serve asa seat fora hollow valvemember i9, which in the form shown is of cup-shaped format-ion, thisvalve member 19 being the main controlling valve between the outletpassage 18 and the inlet passage 20. The valve melnber. 19 is formed, onits upper portion, with a seating face 21, ancLis provided with unbrokenside surfaces 22, which en age, with a sliding fit, the side faces of aead 23, from which depends a,v sloping wall 24- secured to the body ofthe casing ramasse are so arranged as to give the valve member arelatively short movement, while in Fig. 2 the parts are arranged togive it a relatively long movement. lt is, of course,F understood thatthe head 23 is Xed at all times and does not vary its position with theadjustment of the main controlling valve 19. It is the presence of thisfixed head, located in theinterior of the hollow valve member, whichenables the suctional force to ybe created thaty acts as a retarder toprevent the quick return of the valve member to normal position.

It will be noted that the stem 33, which forms a restriction for theentrance of the fluid into the interior of the main controlling valve,operates in a manner so that it is continually cleansed duringoperation, thus prevent-ing the gathering of sediment, which would tendto check its movements and interfere with the proper operation ot thevalve. This point of cleansing the operating parts of the valve appliesequally well to the-parts other than the stem, and, in fact, the valveis so arranged that there is a passage of water at each operation, whichtends to remove any dirt or sediment which may enter, and thus keep theoperative parts in the most desirable condition for satisfactoryoperation.
